Lexical bundles, as building blocks of coherent discourse, have been the subject of much research in the last two decades. While many of such studies have been mainly concerned with exploring variations in the use of these word sequences across different registers and disciplines, very few have addressed the use of some particular groups of lexical bundles within some genres of academy. To address generic variations, this research focused on anticipatory it bundles as a particular structural group of bundles. More specifically, this study chose to investigate range, frequency, and function of these word clusters in applied linguistics research articles and postgraduate writing. Through the use of two big corpora of research articles and postgraduate theses, two text analysis programs, and a functional taxonomy of it bundles, this study found that it bundles were used relatively frequently in both published and postgraduate writing. Functional analysis showed that anticipatory it lexical bundles served a wide variety of functions in both genres investigated. This study also revealed that some anticipatory it lexical bundles commonly used by students in their postgraduate writing did not count as bundles in research articles, both in terms of variety and frequency. As for implications, the study calls for the incorporation of such clusters in L2 and/or EAP (English for Academic Purposes).

The present study investigated the effects of selected presentation techniques including the keyword method, the peg word method, the loci method, argument mapping, concept mapping and mind mapping on L2 vocabulary comprehension and production. To this end, a sample of 151 Iranian female students from a public pre-university school in Islam Shahr was selected. They were assigned to six groups. Each group was randomly assigned to one of the afore-mentioned treatment conditions. After the experimental period, two post-tests in multiple choice and fill-in-the-blanks formats were administered to assess the participants’ vocabulary comprehension and production. Two independent One-Way ANOVA procedures were used to analyze the obtained data. The results showed that the differences among the effects of the above-mentioned techniques were statistically significant in both vocabulary comprehension and production. These findings can have implications for learners, teachers, and materials’ developers.
